Detailed Description

This renderer draws the image along the path of another object spaced at <interval> distance.

This renderer draws the image along the path of another object spaced at <interval> distance. Each image is scaled by <scale> and is rotated to be normal to the path unless _normalToPath is NO.

This prefers PDF image representations where the image contains one, preserving resolution as the drawing is scaled.
